Application filed May 16, 1916. Serial No. 87,883..

Angeles, in the county of Los Augeles and:

tit-ate or (,lalifornhi, have invented new and usefi'll Improrements in 'lable Crumb- Sweepers, of which the following is a spec1fication.

This invention relates to a sweeper and ':aarticularly pertains to a i-sweeplng device for gathering crumbs.

lt is another obgcct to form a device of.

the character described by a al constructaui so ll the various parts will be of simple design and may be readily assembled.

A" )ther object is to provi-sle a simple and ell .ve casing tor the operating meshanism. I

l:\l'l0lll'll' .l. object 1S to provide a specially constructciil handle whlchis mounted upon the casing of the sweeper in an interlocking H'HIHIIIGI so that the component parts of the' handle will be securely held by the same means which fastens the handle to the case. It is a further object to provide a crumb SWBQPQI which is formed of few fparts, may be readily assembled, and menu actured at small cost.

Other objects will appear hereinafter.

The invention is illustrated in the accom panying drawings in which:

Fig. 12 is a fragmentary view in perspective showing the end of the handle member with parts broken away to illustrate the composite construction.

Fig. 13 is a transverse section'taken on the line l3-13 of Fig. 11.

Referring to the drawings more particularly, 15 indicates" the body portion of the sweeper having side members 16 and 17 of approximately twice the length of the end members 18 and 19, A handle 20 is secured to the side member 16 and a detachal'ile'lid or cover 21 is positioned substantially over the 'side members and adapted to pass around the handle member.

Reference being had to Fig. 4 it will be seen that the side walls 16 and 17 are formed with arcuate longitudinally extending outer portions 22 which connect along their lower edges with a horizontally disposed floor 23. The inner edge of the floor members are turned upwardly and form an arcuate shield. 24 which is concentric with the center of rotation of the sweeper brush 25. As particularly show-n in Fig. 6, the members 16 and 17 are of like configuration and are so disposed in relation to each other that their arcuate shield members 2-1 lie upon opposite sides of. the brush 25 and are each equally spaced. from the brush core 26 and concentric therewith. It will be further observed in the same figure that the outer walls 22 extend upwardly the approximate height of the sweeper brush and that these walls are con,- centric with the brush.

The side members 16 and 17 are so formed that their walls 24 do not extend the full length of the walls 22 but terminate short of the ends of said walls. Upturnett cars 27 are formed along the terminating edges of the floor members 23 and are so disposed in relation to the ends 28 of the wall 24 that the false end members 29 and 30 may be held between the ends 28 and the ears 27 The false end 30 is particularly illustrated in Fig. 5 of'the drawing and is shown as being formed with arcuate end portions 31 and 32 which conform to the inner surface of the walls 22 of the side members 16 and 17. The upper and lower marginal edges 33 and 34 of the end 30 are parallel and when in position are adapted to extend horizontally. The upper edge has a pair of outwardly projecting tangs 35 and 36 which are spaced a distance from each'other and an equal distance either side of the longitudinal center of the sweeper. The lower edge 34 of the end member is formed with an outwardly extending tang 37 which is of a length similar to that of the upper tangs. The tang 37 is formed with a semi-circular perforation 38 having its outer edge 39 parallel to the end of the tang for a purpose which will hereafter be set forth. While I have thus described the false end member 30, it will be understood that the member 29 is of a similar construction and mounting.

The brush 25 is cylindrical in shape and is formed with a central core or shaft 26 which is shown as comprising a pair of wires twisted together in a manner to securely hold the bristles in place and provide a rigid central axle for the brush. The terminating ends of the shaft 26 are adapted to extend" through openings 40 in the center of the false endmembers 29 and 30. Spur gears 11 are secured upon the ends of the shaft 26 after they have passed through the bores 40. Gears 42 are mounted upon rotating spindles 43 upon which the tractor wheels 44-47 inclusive are fixedly mounted. When the ends of the spindle 43 are in position within bores 48 and 49 formed upon opposite sides of the bore 40 in the members 29 and 30, the gears will be in mesh and the movement of the tractor wheels will act to rotate the brush 25.

. The spindles 43' are mounted at their outer ends in perforations 50 and 51 formed in the end caps 18 and 19 which are provided to incase the gears and the tractor wheels. As particularly shown in Fig. 7 of the drawings, the end casings are formed with an end wall 54 which is of substantially the same inner marginal. configuration as that of the false walls previously described. A flange 55 extends outwardly and at right angles to the end wall 54 and is adapted to fit snugly over the walls 22 and the floors 23 of the side members 16 and 17. A pair of rectangular slots 56 and 57 are formed in the lower horizontally disposed. portion of the flange through which a portion of the frictional tires 58 with which the tractor wheels are provided, extend to engage the surface being swept.

permit its being conveniently grasped. however, is novel in construction in that it is is in a single plane and which has arcuate downturned flanges 61 and 62 which, when inposition, conform to the surface of the walls 22 of the side members 16 and 17.

An open-ended slot 63 is formed at substantially the longitudinal center of the flange 62 and is of the proper dimension to accommodate the handle portion 20 mounted within the side member 16. The cover member 21 is preferably formed of sheet metal having an inherent resiliency so that its flange portions will grip the sides of the sweeper when in position It will be noted that there are no separate securing or fastening members used in the construction of this device. This feature of design has been attained by forming semicircular engaging perforations 64 and 65 adjacent the ends of the arcuate walls 22 of the side members and the semi-circular opening 39 formed within the tang 37 of the members 29 and 30 as hereinbefore described. These perforations are adaptedto register with obtrusions 66, 67 and 68 which are formed as a part of the casing members 55. The obtrusions are stamped out of the metal and are in the shape of a ortion of a cone having a square base, said ase being adapted to positively engage the square face of the perforations with which it registers.

In order that the device may be easily handled and operated the handle 20 is provided and secured in the manner which will presently be described to the arcuate wall 22 of the side member 16. The handle 20 may be of any desired configuration which will composed of a pair of telescoping members 69- and 70 which are arranged in relation to each other as particularly shown in Fig. 13 of the drawings. In this figure it will be noted that each one of the members is composed of body portions 70 and 71 and side flanges 72 and 73 which overlap each other I and are of a corresponding width. The side flanges 72 and 73 of each of the members 70 and 71 extend longitudinally a distance from the body portion of the handle and terminate within tangs 74c77 inclusive. These tangs are of a width slightly less than that of their main side portions 72 and 73 and thus form a shoulder 78 which abuts against the surface of the member 22 when in position. As particularly illustrated in Fig. 10 the tangs are passed through rectangular perforations 79 and 80 formed parallel to each other and through the arcuate wall 22. When so positioned they are bent in oppositedirections to each other to secure them in place. v

When the device is to be assembled, the

l. positioned between them with the terminating-ends of the core 26 extending through their openings as previously descrlbed. Next, the driving gears 41 are positioned upon the ends of the core and suitably secured thereto. The side members 16 and 17 are then positioned overthe arcuate ends 31 i and 32 of the false end walls 29 and and ressed inwardly until said walls are gripped between theends 28 of'the arcuate members 24 and the ears 27 which areformed integral with and upturned from the floors 23 of the compartments 81 and 82. outer walls 22 have been brought to regis ter with the arcuate ends 31 and 32 of the falseend members, the tractor wheels are positioned with one end of their spindles 43 extending within the perforations 4 8 and 49 and with their gears 42 in mesh with the gear 41 mounted to rotate with the core 26 of the brush. When the tractor wheels are in position, the end caps 18 and 19 are pressed over the assembled ends of the structu re previously described. As the end caps are pressed into position, the obtrusions 66-458 inclusive will be brought to register with the semi-circular slots 64, 65 and 38 which are formed within the ends of the side members and the false end members, respectively. When the square shoulders of slots the end caps will be securely held and l the operating mechanism will be adequately incased. The device is now so assembled that all of its parts are rigidly fastened in a permanent. manner in relation to each other. The lid member 21 may now be pressed over the arcuate surface of the outer walls 22 of side members 16 and 17 and when so pressed the resilient action of the flanges 61 and. will cause the lid member to be securely held in a closing position and in a manner to allow its ready removal.

In theoperation of the device, the tractor wheels are allowed to bear against the surface to be cleaned and while the operator manipulates the device by the handle it may be moved forward and backward over the surface. The tires 58 with which the tractor wheels are provided will. act in a manner to cause the wheels to rotate and they in so doing will rotate their individual gears 42. The gears 42 in mesh with the gear 11 and will thus effect the rotation of the sweeper brush while the device is being moved in either direction.

Reference being had to Fig. 9 of the draw-- ings, it will be noted that the brush mem ber is rotated in either direction, it will have a sweeping action. upon the surface beneath it and will throw the particles swept iutnvardly and over the walls 24 into the comparti'nents S1 and 82.

When the a The. accumulation of crumbs and other sweepin s may be'readily removed from the sweeper 'y slipping thelid member 59 from its seated and resillently held position over the arcuate faces of the side walls 16 and 17. The chambers or troughs 81 and82 are so formed that the sweepin s may be readily removed by inverting t e device.

It will thus be seen that I have provided a sweeper for collecting crumbs and like sweep' t which is formed of few parts of simple esign and whichv may be readily assembled and which is easily manipulated roduce the desired result.
